After spending a huge amount of time spackling the imperfect (by our standards) plaster walls and sanding the Master Bedroom walls down, we attempted to apply a coat of Dulux ICI Wall Sealer on the wall in preparation for adding the Dulux brown paint. It was a DISASTER; even after we added water as the product and hardware store suggested it was still too thick and caked on the wall in a chunky mess before we could even re-roll over a stripe. We finished after adding more water, left the house and can only hope when we return tomorrow morning it will have miraculously flattened out to what we were expecting from the expensive product. We haven’t been at all convinced about the Dulux products so far. Our experience with Nippon in the Laundry Room and Kitchen was pretty good.
